A person pulls a toboggan for a distance of $35.0 \mathrm{m}$ along the snow with a rope directed $25.0^{\circ}$ above the snow. The tension in the rope is $94.0 \mathrm{N} .$ (a) How much work is done on the toboggan by the tension force? (b) How much work is done if the same tension is directed parallel to the snow?

Key Concepts

Work

Work is a measure of energy transfer that occurs when a force causes an object to move. It is defined as the product of the force component in the direction of displacement and the magnitude of that displacement. This concept is central in mechanics and energy studies as it links forces to changes in an object's kinetic or potential energy.

Force Decomposition

Force decomposition involves breaking a force vector into components, usually along axes aligned with the direction of interest (such as horizontal and vertical). When a force is applied at an angle, only the component parallel to the displacement contributes to the work done, making it critical to determine this component through trigonometry.

Dot Product

The dot product is a mathematical operation that multiplies two vectors to yield a scalar. In the context of work, the dot product of the force and displacement vectors, which includes the cosine of the angle between them, provides the correct calculation for the work done by that force on the object.
